I am joining a .csv file to shp layer and it goes well except all the values from the .csv file disappear (there's NULL in the attribute after the join)?
I don't have X & Y coordinates, but I'm combining it with a place name.
For example, shp files contains text columns (example made in excel on purpose):
And the .csv file contains also additional info
I also tried to add these columns straight into the shp layer attribute table to fill in the info there from the csv file by hand, but I couldn't fill in any information. There's also NULL (in both form view and table view options), but I can't edit the cell at all. I can only edit the cells that already existed in the shp file itself.
What could be wrong with this as well, should I enable editing separately for these new columns?
I'm quite a beginner with QGIS, but this is really something I just can't figure out.
